Africa, The Nile River

"The river Nile. Here is the longest river in the world. It empties into the sea at seven points. During the whole year, there are never clouds or rain; hence the inhabitants are experts in astronomy. Every year the river overflows for a period, which makes the land very fertile, as though manure has been spread on the fields. That is why they cultivate five grains and reap their harvest a hundredfold. The country is renowned for its wealth and abundance."
